*These units were armored regiments during World War II since the 2d and 3d
Armored Divisions were not reorganized, as were the others, on 15 Sept. 1943.

Component Elements of the Airborne
Divisions in World War II

The first and second lines for each division show the organization prior to
1 March 1945, and the third and fourth lines show the composition after that
date. All units omitted in the third and fourth lines were inactivated or disbanded
on 1 March and all additional units listed were activated or assigned on that
date.
